Shootout of Nos 6sn7 tubes


I will have shootout between TS BGRP, RCA vt231, KR vt231, Syl vt231, Raytheon vt 231 and "Bad boy" next weekend.

If I get MELZ 6N8S 6SN7 Metal Base next week, then I will also include it in shootout


RCA5691, Psavne Acme 300B, Psavne Acme 805 are also being used in Line Magnetic 508 amplifier.

Speaker will be Lansche 4.1 with plasma tweeter.

Digital source will be Dave and HMS fed by ripped CD stored in ssd drive of Cocktail audio x30.


I will play

Eva Cassidy's 'Autumn Leaves"

"Trinity Sessionn " by Cowboy Junkies

For classical orchestra, "Trittico" directed by Fennel.

"Still harry after all these years" will be for fusion jazz.

Any more suggestion gentlemen and ladies.

6N8S from Ukraine are also good tubes at excellent value under 100$ per pair.

But I enjoy full bass out of Melz 1578.

Some Melz 1578 has a problem with noise.
Thanks. It looks like they come from extra stock or liquidated Old Chen preamp stock. See https://www.hifi-amplifiers.com/en/oldchen-tube-amplifierslaochen-c-118/oldchen-c1-hiend-6h8ccv181se...  gd-parts link for the tube goes to AliExpress, where they show 1000 pairs,
for the price of these tubes they offered a more tube sound than the new JJ Tesla 6SN7 tubes I was using.  More musical, more dimension, a nicer more relaxed sound in direct comparison in the preamp.  Have not tried them in my hybrid tube power amp yet or to the many 6SN7 tubes I already own.
